MACHINE FOB DISPENSING OIL Application filed January 17, 1925. Serial No. 8,034.

The invention relates broadly to coin controlled dispensing machines and particularly to machines for dispensing gasoline, oil, etc, for filling station use.

One of the objects of the invention is to provide a simplified and improved gasoline dispensing machine that can be operated without an attendant,

which is of great con venienee at night when the usual day attendant is not present and the station is otherwise closed. These machines also have great utility for outlyi try use.

ng localities and coun;

Another object of the invention is to provide improved coin control lockin means of relatively simple venting operation of I proper .coin or coins the machine.

Another object is full-stroke mechanism construction for prethe machine until the" have been inserted into provide. improved for compelling a full operating stroke in one direction of the operating handle. This revents the operating handle from being oscillated or jiggled back and forth to obtain more than the purchased amount of gasoline. Another object of theinvention is to provide a liquid dispensing machine in. which coins of difi'erent denominations may utilized to operate it.

A still further object of the invention is to provide means for-preventing fraudulent use of slugs 1n the'machme.

In the drawings illustrating a embodiment of the invention: Fig. 1 shows a fragmentaryview casing with a portion broken away for the purpose of illustrating the operating-mecha-fi' nism.

taken on line of led view of the entire ,tion thereto and is The machine comprises a liquid dispensing member represented by the rack 11 which is operatively connected to a pump of any known construction. This pump discharges through the usual filling hose, not shown. This li uid dispensing rack is suitably guided orvertical reciprocation, and at its upper end, connects with the coin controlled operating means, which I shall now describe.

Within the casin 12 a pair of standards 13 and 14, provided to carry the operating mechanism, are supported on a cross brace 15 secured to the inner side of said casing in any convenient or approved manner.

A driving shaft 16 extends rotatably through bosses 17 on arms 18 of the standards. A ratchet wheel 19 is fixedly secured to this shaft, abutting the inner side of one of the bosses 17 to prevent lateral displacement of the shaft 16 in one direction. This ratchet wheel, together with its pawl which I shall describe presently, constitute the looking means for preventlng operation of the. machine until the proper coin or coins have been inserted.

To the left of this ratchet wheel 19 a sprocket 21 is secured to the shaft 16 in spaced relation to said ratchet wheel to provide means of driving another shaft 22 which will shortly be described.

To the left of this sprocket 21 on shaft 16 a pinion 20 is fixedly secured in spaced relafirovided to drive another shaft 23 which wi bepresently'described.

- To the outer end-of'thisdriving shaft '16 an of the other direction and providing means for shaft '22 insubstantiallythe same plane as the inner side of boss 25 on the standard and: prevents lateral displacement of the shaft 22 in one direction while a collar 26 P is secured to said shaft to abut the other boss 27 to prevent lateral displacement in the opposite direction. This latter ratchet wheel together with its associated pawl constitutes a full-stroke mechanism for com- I operating member'or handle in the form of Y atcrank 16 is secured, fixedly abutting the outer side of the one of bosses 17 to prevent klateral displacement of the shaft .16 in the sub rack 11. A gear 31 is also secured to said shaft 23 and meshes with the driving pinion '20 on driving shaft 16. This shaft 23 is held against axial displacement by thepinion 29 at one end and a collar (not shown) at the other end. 7

A flat boss is formed on the standard 14 above the shaft 23 to which is secured a bearing bracket 32 which carries a compound pawl 33 pivotally mounted thereon by a shaft 34, the pawl being disposed in position to have its noses 35 and 36 engage the ratchet wheels 24 and 19 respectively. A lever 37 is secured to the other end of the shaft 34 to carry a weight 38, this weight normally tending to release the upper pawl nose 35 from the locking ratchet wheel 19 and to project the lower pawl nose 36 into the teeth of the full-stroke ratchet wheel 24. The efi'ect of the weight is normally overcome, however, by the coin trip mechanism which holds the weight in elevated'positiom'as I shall pres: 'ently describe. a

An arm 39integral with the compound qpawl carries an extension bolt 41 to the end of which a tension spring 42 is secured.

The other end of the spring is secured to the standard 14 by means of a pin or the like. This spring is disposed to act as a biasing spring, being thrown to one side and then. the other of the pivotal center 34 by, the movementof'the double pawl. This spring holds either one end or the other of the pawl in engagement with its respective ratchet wheel. The spring is not of. such tension however, that it can oppose the action of the'weight 38 when the latter is trippe for swingingthe pawl downwardly.

A slotted adjustable gauge 43 is secured to the rack 11. in any approved manner, as for instance by a plurality of set screws 43' n I illustrated in Fig. 1 and an indicator pointer 44 extends outwardly from said gaug 43 0 register with graduations 44 on the outside of the casing 12, to indicate the amount of gasoline or oil being dispensed for a certain rice. p For example, assuming the machine to'be of the type for dispensing gasoline in 50 cent quantities and gasoline-is selling at 20 cents per gallon the adjustable gauge 43 is i set to dispense 2 gallons for every actuation of the operating crank. Should the price change the adjustable gauge is adjusted to give fifty cents worth at the current price. Fifty cents worth of gas at the various prices is indicated on the graduations 44'.

A block 45 secured to the upper portion of the casing carries a bearing bracket 45'. Mounted thereon is a centrally pivoted lever 46. A rod 47 is pivotally secured to said lever 46 and extends downward through a guide sleeve 40 to engage the end of the double pawl 33. a

Coin receiving slots or conduits 48 and 49 lead to a coin receiving receptacle (not shown on the drawings) at the lower end of the -casing 12, where a door 51 (Fig. 8) is provided to Q'lVGBCOESS to said coin receptacle. A trip latch is provided adjacent the lower end 49 of the conduit 49 and comprises a centrally pivoted lever 52 mounted in bearings 50 and normally held in the position shownin Fig. 5 by'a suitable torsion spring 52'. One end of said lever supports the weight 38 and the other end extends through a slot into the conduit 49 to be operated by a coin falling against it. The said weight 38 is hung from lever 37 by a rod 53 or the like,-which.is guided in an aperture in an angle iron 54 secured on conduit 49. This weight need only'be com- I I latch 52 out from under the edge of the -'.we1ght. I

The conduits are bent as shown at 55 in Figs. 2 and 3 and have slots 56 and 57 provided at this bent portion to eject small coins such. as pennies, nickels and dimes and a magnet 58 is secured adjacent these slots to prevent the device from being operated by slugs or the 1ike.-

The fifty cent slot 49 discharges into the outer. bottom slot49 and the twenty-five --cent slot 48 discharges alternately into the front slot 49 and into a rear slot 60. A. gate 61 is pivoted in an opening 62 in the lower end of the twenty-fivecent slot to perform this alternate directing function. The lower end of the gate 61 has small divergent ears 61' 'which are adapted to be struck by the coins for throwlng the gate to one side or the other. p In the operation of the machine, with the parts in the position shown in Fig. 2 a fifty cent piece is inserted' in the conduit 49 and passes downwardly engaging with one end of thedouble lever 52 causing it to release the-weight 38 which carries the lever 37 downwardly causing the nose 35 of the double pawl 33 to disengage with the teeth of the ratchet wheel 19, thus unlocking the operatingcrank for rotation in a clockwise direction.

The crank is then revolved, driving the shaft 16, whose motion ,is transmitted to conduit 49 it will drop through the slot 57' shaft 22 by means of the chain'30 which is trained over the sprockets 21 and 28 on the respective shafts. I

The pinion 20 on the driving shaft 16, meshing with the gear 31 on shaft 23 transmits rotation to said latter shaft. The pinion 29 on shaft 23 which is in mesh with rack 11 causes the rack to rise and gasoline to be ejected from the pumping cylinder.

During this tinie the pawl end 36 is playing in the teeth of the full-stroke ratchet wheel 2i. Thereis thus no possibility of reversing the direction of rotation of the crank handle until the full'pumping stroke of the rack 11 has been completed. This avoids any possibility of oscillating the crank handle back and forth to make successive short pumping strokes and thus obtain more gasoline than the purchased quantity.

The slotted adjustable gauge 43 has previously been set to correspond to the number of gallons of gasoline fifty cents will buy at the current market price and as it travels upwardly it engages an arm of the lever 46 causing the opposite end of the arm to travel downwardly carrying with it the rod 47 which engages the nose 35 of the double pawl 33, pressing it downwardly into engagement with the teeth of the ratchet wheel 19 and thus preventing any further upward travel of the rack. As this nose engages these teeth the other end of the compound pawl disengages from the teeth of the ratchet wheel 24, thus leaving the crank free to turn in a counter-clockwise direction.

A locked door (not shown) is provided in the casing 12 adjacent the compound pawl to permit of the insertion of a pin or the like to disengage the pawl so that the device may be operated without a coin if desired.

As stated above the slot 49 is provided to receive fifty cent pieces but if two quarters are to be used they must be dropped successively into the conduit 48. As the first quarter passes the gate 61 it will be deflected into the rear passage but in passing into this passage it will strike the adjacent ear 61 and throw the gate so that theneXt quarter will travel through the conduit 49' leading to the trip latch 52 thus disengaging it in the same manner as the fifty cent piece. The latter quarter in passing into the coin slot 49 will throw the gate 61 back to its original position. 1

If one of the quarters is dropped into the provided therein but on the other hand when the quarter is dropped into the conduit 48 it lar details herein shown and described, as it will be obvious that the foregoing is only an exemplary embodiment of the invention. Having described my invention what I claim is: 1. A'coin controlled liquid dispensing apparatus comprising a vertically movable pump actuating member, rotatable actuating means therefor, a pair of oppositely acting ratchet wheels operatively connected with the actuating means, a double acting pawl constantly engaged with one of the ratchet wheels, coin controlled means for actuating the pawl to a position where the, actuating means may be free to rotate in a clock-wise direction, a vertically movable rod supported above the pawl, and means operable upon the pump actuating member reaching its limit of travel in an upward direction for lowering the rod against the pawl to disengage one of its arms from one of the ratchet wheels and cause the other arm to engage the other ratchet wheel whereby to allow counterclockwise rotation of the actuating means.

2. A coin'controlled liquid dispensingapparatus comprising .a vertically movable pump actuating member, rotatable actuating means therefor, a pair of oppositely acting ratchet wheels operatively connected with the actuating means, a double acting pawl constantly engaged with one of the ratchet wheels, coin controlled means for actuating the pawl to a position where the actuating means may be free to rotate in a clock-wise direction, a pivoted lever supported above a the pump actuating means, a vertically movable rod above the pawl and having one end pivoted to the lever, and an abutment on the pump actuating member and arranged to engage the lever whereby to move the rod into engagement with the double pawl to disengage one of its arms from one of the ratchet wheels and cause the other arm to engage the other ratchet wheel whereby to allow counter-clockwise rotation of the actuating means.

In testimony whereof I affix my signature at 10 South LaSalle St., Chicago, Illinois.
